Across
  1. 3. an atom or molecule with a net electric charge due to the loss or gain of one or more electrons
  2. 5. the force of attraction or repulsion of magnetic materials
  3. 7. field the region around a magnet where the magnetic force is exerted
  4. 9. field a region around a charged object where the object's electric force is exerted on other charged objects
  5. 11. pole one of the two ends of a magnet where the magnetism seems to be connected
  6. 16. charge more protons than electrons
  7. 17. force an attractive force that acts between any two objects
  8. 18. a form of energy caused by the movement of electrons
Down
  1. 1. an instrument for detecting and measuring small electric currents
  2. 2. a material or an object that does not easily allow heat, electricity, light, or sound to pass through it
  3. 4. a material that allows heat and electricity to pass through it
  4. 6. energy energy caused by the movement of electrons
  5. 8. a measure of the extra positive or negative particles that an object has
  6. 10. a machine that converts mechanical energy into electrical energy
  7. 12. field the region of space surrounding a body in which another body experiences a force of gravitational attraction
